@sjb which part of the GSE do you think was at fault here?

@wolf480pl Perhaps the blast wave from the engine fire dislodged something on the new pad? (Broke a sensor cable, produced a faulty reading etc.)

@sjb I've heard EJ speculate that the deluge system may've had an issue (I imagine sth like not being able to provide enough water for the duration of the static fire).

But your hypothesis sounds more likely.

@wolf480pl I'm only going on process of elimination: it's less likely to be the tanking system or the deluge etc. because they've tested those already. The new thing is the actual ignition and consequences of that like the pressure wave. ~0.5 seconds is enough for those consequences to be felt at least.

@wolf480pl Oh yeah, other factor: the new pad is new. I would not be surprised with problems in the pad.

@sjb hmm ok but like, which parts of the pad wouldn't've been tested to a similar level during the tanking tests?

the support arms, hold down clamps, and QDs would be seeing the same kind of load... unless exhaust was recirculating up above the engines, I guess

@wolf480pl I'm thinking more transient loads and pressure waves bouncing around the system.

@wolf480pl Or literally just a badly soldered connection somewhere in the pad that comes apart when 2 million decibels are fired at it.

@sjb hmm ok, but you know what else is new?

The booster.

If the exhaust / pressure waves could knock apart a bad connections in the pad, it could also knock apart a bad connection in the booster.

@wolf480pl SpaceX said "the 10-engine static fire ended early due to a ground-side issue," which I'm assuming means not booster.
